None multiple vertex (GPS) coodinates

Hello, I generated two cylindrical volume sources with GPS. I turned on gps verbose level to max as: /gps/verbose 2. I also turned on multiple vertexing as: /gps/source/multiplevertex true

When I shoot a gamma with /run/beamOn 1 , I expect to see "two" primary vertex information for two gammas from two volumes. Visualization shows two photons. However only one vertex information is printed. Is this the normal behaviour?

In addition, I also want to to be able access this information in my EventAction so that I can record primary vertex positions. How can I record the primary positions for ALL gammas from ALL source volumes?

thank you very much, ahmet.
